大断面浅埋瓦斯隧道穿越私采巷道处理方案

Treatment Plan for Large-section Shallow-buried Gas Tunnel Passing Through Private Mining Roadway

在川中背斜穹窿地带,铁路隧道施工过程中经常会遇到浅埋泥岩夹煤层的隧道,本文结合成自高铁长征隧道施工实际,对该隧道穿越私采巷道施工做简要介绍,为今后类似浅埋隧道施工提供一些借鉴。

In the dome area of the central Sichuan anticline,the construction of railway tunnels often encounters tunnels with shallow mudstone interbedded with coal seams.This article combines the actual construction of the Long March tunnel on the Chengzi high-speed railway,and briefly introduces the construction of the tunnel through the private tunnel,and provides some reference for the construction of similar shallow tunnels.
